T0 all w7wm z't 12my concern:

Be it known (filmt wo, MARTIN V. JORDAN and CARY O. COLE, oit-izens ot' the United States of A1nericu, resicling at Letts, in tho county of Louisu und Stute of Iowa, hzwe invented cortaiu 110W und usoful Improvements in Corn-Planters; und wo (l0 l1ereby declare oho following to be u full, clear, and exaot description of tho invention, such as Will enablo others skilled-in the art to which it appertains 130 make und use the same, reforenoe being had to the aceompanying dmwings, und 130 lotters o1 figures of roferenoe marked thereon, which for1n a part of this specification.

Our invention relates t0 certain new und useful improvoments in corn or seed planters; und it consists in the improvements hereinafter described ancl set forth.

In tl1e accompanying drawings, Figuro l is a sido view, partly in soction, of a planter coustructed in acc0rdanco Witl1 our invention. Fig. 2 is zu plan viow. Fig. 3 is a detail sectional viow of the secd hopper und spout. Fig. 4 is a plan view of oho seod-slide, und Fig. 5 is a detuil perspective view of tho end of tho seedslide operating-lever.

A reprosents an uppor frztme, Whioh con sists of a series of longitudinal beurns, a a, which am connected to each otl1er at their encls by curved 1netallic braces a a. The center longitudinal beams, a a, havo attacl1ed at their forwurd end tl1o draft-tongue A, und at their rear ends the drivers soat A.

B roprosonts a oentral axle, whioh rotates freo1y in boxes attached to the under sides 0f the beums a, the outer en ls of tl1e aforesai(l axle boing f0nned into spindles upon whicl1 rotate tl1e hob of tl1o supporting-wheels B. The axle Bjust beyond tl1e longitudinal beams a of tl1e frmne, is provided near each end witl1 collars which aro rigidly attached thereto, said collars lmving projeoting portion Z), to whiel1 am pivoted spring-pawls which engage with ratchot-wheels c, attachod to the inner sides of tl1o hubs of tl1e wheels, tl1e teeth of the rutchet-wheels being so placed that when the planter is druwn forward the axle Will be rotatetl, und will remain stationary wl1on the wheels am moved in an opposite direotion. T0 the center of tl1e axle, und between tl1e beams a a, ure located a series 0f ratchet-disks,

SorialNo. 179.070. (N0 ll]()ll0l.l

C, whiol1 aro of the same diameter, but are provided on thoir periphcries with teetl1 whioh am located at difforent distances fron1 euch other, so us to provido ior dropping tl1e gmin or corn ut different distuncos, as will be hereinul'ter set forth.

D represents tl1o lower fmme, whiclh is pivotally uttaohed to dopemling burs 01 hangers d, which a1e ucljustably coimocted to the upper fmmo in Front of the axlo, und by providing this adjustablo connection between the parts tl1e depth whicl1 tl1o runners 011 shoes Will entcr oho ground can loe regulated.

The reur portion of tl1elower t'rame, lbet ween the seed-hoppers, is provided with an upwzmt ly-prqjeoting bar, e, to whicl1 is pivotecl the min ofu cmnk-lever, E, said omnk-lover hav ing u puwl whioh engages with u toothed segment attachecl to tl1e upper imme at tl1e right band of tho drivers saut, said cmnk-lever being for tho purpose of ruising tho rear end 0f the lowor frzune, so that it can move freely over obstructions 01 for deprossing tho sonne,

so that the heels of tl1e sl1oes will enter deeply into the ground.

Tl1e seed-spouts F, wl1ich a1e located at the l0itl ends of the shoes, aro preferably open at tl1e back portion, und at their lowor ends 01 l1eels um eut away, as shown at f so tlmt tho grain may froely pass f1om the sume, und tl1ey are extenclecl reuvwztrdly at their lower ends so as t0 provido rearwurtlly-projecting portions f, to which am pivotally uttaohed de-- pending zmns G, whioh am curved rearwardly und oarry at their lox;vor ends groovod cove1= ingwvheels g, which move in t line with the heels of the seed-spont's. These arms G are also connocted neur thoir central portions to tl1e seed-spouts by springs g, whieh caus'e tho samt: to press firrnly upon the ground, so as to thoroughly cover tho seed, und said springs will allow the aforosaid arms und. whoels to rise, so as to move over obstruo tions without mising tho heels of the shoes out of tho ground.

The seed-hoppers H. are secnrely attachecl at their lower sides to tl1e lower frame, immediately ubove tl1o sood-spouts, und l1avo spouts at their rear aml front sides, through which tho soed-slicles I will pass, und abovo the slide und to the l1opper is attaohed a brush, i, be

ICO

neath which the seed-siide will reciproeate, seid brush removing the surplus seed from the opening in the slide.

The hopper-bottom, as shown in Fig. 3, is provided Wibh an adjustnble section, i, for inoreasing or diminishing the size of the opening berein, and the size f this opening k can be varied by turning the set-serew h. 'lhe seed-slides I, which reciprocate above the seed-spouts, are connected t0 each other by one or more transverse bars, I, so bhat; they will move in unison, and to the center portiou of the forward bar is attached the operatingbar J, the forward end of whioh is removably eonnected to a crank-lever, J, whioh is pivoted to the mein frame so as to eontacb wibh the ratehet-disks O.

'lhe bottom of the seed-hopper H, nenr the rearportion of the seed-spouts, is provided With s1ots, whioh are loeated ab one side of the same, through which Will pass the upper end, m, of a swinging valve, K, pivoted as shown, and its upper end is adapted to e1'1gage with the seed-slide I, whioh is provided With a longitaudina1 recess, n, through whieh the upper end ot" the valve K passes. Ihe vaive K is provided near its upper end With a spring, o, whieh has a tendency to keep the lower end of the valve K against the seed-spout.

By the constrnetion hereinbefore set forth, when the seedsiide is reciproeated the proper amounb of grain will be onrried by the opening K berein under the brush i, and will-feil into the seed-spout, and when seid seed-slide is moved forward the noteh 01 recess n berein will engage with the upper end of the pivoted valve K, so as to open the 1ower end und allow the grain to fa11 in the furrow made by the shoe.

The angle-bar J, to whieh is attached the barJ of the seecLdropping meehanisnn, is pivoted in front 0f the ratachets-disks, und its depending member p is provided with a series of perforations, in which the end of the bar may be plaoed, to vary the reeiproeation of the seed-slide. The angle-bar J is supported on a central shaftz, j, which has end bearings in oastings attached to the upper frame, und

said shafi: is eneireled by a spiral spring, the ends of which bear againsb the upper men1ber, p, of the angle-bar J ibl]d the main frame, so as to hnve a tendeney 60 throw the member P downwardly and against the ratchet-disks.

The arm P is made in tw0 parts, es shown in Fig. 5, so that the parts can be adjusted one upon the other transversely, so that the end may be placed so as to engage with the different disks. The upper member, p, besides serving as a bearing for the spring, can be used as a fools-1ever for throwing the crankarm J out of gear.

In eonnection Wibh the seeddropping mechanism hereinbefore described, we propose to employ a eheek-row meohanism, which will be attached to the lower frame and operate in eonjunelaion with the crank-arm J.

l. In a eorn-planter, an upper frame provided with a eentral ax1e to whieh are attaehed ratcheb-disks, a crzmk-lever having a horizonta1 adjustable portion, and pivoted 130 the frame so as 110 engage with one 0f seid disks,

und having a portion depending below seid frame and disks, a bar connecting the Same directly with a seed-slide, and a spring for holding the 1ever against the disks, substantially as shown, an for the pnrpose described.

2Q In a seed-planter, the combination, with the ratchet-wheels O and crank-lever J, having a horizontal adjustable Portion, of seedslide conneetions, 1eeiprocting slides provided ab their sides with notches, the va1ve K, having npwardly-projecting portion m, which engages with said noteh es, and a spring,o, substantiail y es sh0wn, {und for the purpose set foroh.

3. In a seed-planter, the rotary nxle provided with a scries of ratchet-disks rigidly attach1d thereto, a crank-lever, J, havin.g a depending member, p, W hich is conneeted to the seed-slide, and a me1nber, P, nmde in two arts, so thai: its rear end ean be adjusted lateraily, so as to engage with either one of the series, of ratehet-disks, in combination wich seed-planbing devices conneeted to nnd aetu ated from the lower end of saiddepending member, substantially as shown.

In testimony whereof we afiix 011 r si gnatures in presence 0f two witnesses.
